currently points to /etc for the system, and dedicated "data" directories
for common/user (the system directory should get a dedicated "data", too,
though).
* Added B_USER_CACHE_DIRECTORY (in config/cache).
* These additions were discussed some years ago, but I just had a good reason
to use them :-)
* Coding style cleanup.

- Fixed deadlock in xsi_sem_undo - RecordUndo
- Fixed issue in xsi_sem_undo: if the semaphore set does not exist
anymore, ignore the request but do remove the process from the sUndoList,
which wasn't previously done.
- free() in ClearUndos was called with interrupts disabled
- when a semaphore set ends to exist, remove all it's sem_undo request as it's ID
will be reused in the future.

* sCopied wasn't needed anymore due to the sManagedEnviron variable.
* Minor cleanup, added a description to copy_environ_to_heap_if_needed().

the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.

by myself:
* renamed xsi_do_undo() to xsi_sem_undo() (there is more to XSI than sems).
* Fixed coding style issues in sys/sem.h and xsi_sem.cpp.
* Added _kern_*() syscall prototypes to syscalls.h.
* Added a TODO in xsi_sem.cpp and xsi_semaphore.h about moving union semun to
a shared header.
* Made the team::xsi_sem_undo_requests int32 - due to padding, it would have
needed 4 bytes anyway; please always use specific types over int/short/long.
* xsi_sem_undo() now checks if it needs to do anything - the calls in team.cpp
no longer needs to do this.

header.
* Added fields necessary to make it possible to retrieve more than one
dirent from the underlying file system.
* Unless some app creates a DIR on its own to it to feed readdir(), this
change should be binary compatible. If we find an application misbehaving,
we can still make it a GCC4 only thing.
* fs_attr/fs_index/fs_query now all use readdir() directly (as that one
contains the logic to iterate through a number of dirents in userspace).

a flattened argument/environment buffer now. This simplifies the work
for the kernel a bit, since it can just copy the buffer and check
whether it looks OK instead of messing around with individual strings.
The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
When more arguments are passed, we fail with a proper error code
(instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
name, which is not correct.

and remove the then unneeded mutex_init() for them.
* Remove the workaround for allowing uninitialized mutexes on kernel startup.
As they are all initialized statically through the MUTEX_INITIALIZER() now
this is not needed anymore.
* An uninitialized mutex will now cause a panic when used to find possibly
remaining cases.
* Remove now unnecessary driver_settings_init_post_sem() function.

- *pathconf() now uses statvfs and fs_info data when appropriate. It should also check for file type though, some only apply to directory or others.
- added confstr(_CS_PATH) with a sensible default.

vm_page_write_modified_pages(), save that it only writes pages in the
given range.
* Added vm_page_schedule_write_page_range() which schedules all modified
pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25620 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the pthread_cond_t internals public. This is necessary to support
process shared condition variables. Fixed initializer macro.
* Made the pthread_rwlockattr_t structure opaque.
* pthread_t is no longer typedef'ed to int. It's the pointer to the
internal _pthread_thread structure.
* Removed __get_pthread(). pthread_self() can be used instead.
* No longer tunnel the pthread exit value through Haiku's thread exit
value. We do have a separate field in the _pthread_thread structure
for it, now.
* Handle detaching of threads correctly.
* pthread_rwlockattr_{g,s}etpshared() use the
PTHREAD_PROCESS_{SHARED,PRIVATE} constants, now.
* Commented out yet unsupported structures (barriers, spinlocks).
* Rebuilt APR optional package. The pthread changes weren't binary
compatible.

to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

particularly efficient.
* pthread_mutex implementation:
- Removed the pthread_mutex_t indirection (the type was a pointer to
the actual structure which was allocated on the heap), as it made
sharing the mutex between processes impossible.
- Removed the distinction between process shared and non-shared
mutexes. Benaphores work just as well in shared memory, so we always
use them.
* Fixed some static initializer macros. PTHREAD_COND_INITIALIZER is
still broken, since it doesn't work in C code.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25481 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added stack_address and stack_size to thread_creation_attributes,
which allow to specify the stack size or the stack to be used for the
new user thread.

* Changed the semantics of unnamed semaphores. Before parent and child
of a fork() would always share an earlier created semaphore. Now we do
that only, if the "shared" parameter of sem_init() was true. That's
still not quite the behavior Linux and Solaris have, but should be
perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
semaphore is leaked when no one explicitly destroys it (just as with
named sems).
* Enforce per-team and global semaphore number limits.

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

that does not rely on the Be API TLS anymore, and is also more compliant
with respect to the lifespan of the key specific values.
* It supports up to 256 different keys, which is equivalent of the solution
that FreeBSD offers.
* The main thread now also gets a pthread_thread structure.
* Reenabled the POSIX suite test pthread_key_delete_2-1 as we now pass it.
* This also fixes bug #1642.

and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.

- Moved most file_system_module_info hooks into separate structures.
Those that operate on mounted volumes to fs_volume_ops, those
operating on a vnode to fs_vnode_ops.
- Got rid of the fs_volume, fs_cookie, fs_vnode typedefs. We use void*
again.
- Instead of a void* volume and node cookie hooks are passed a
fs_volume and fs_vnode structure pointer, which contain the cookie
and an ops pointer (fs_volume a few more things).
- The VFS {new,publish,get,...}_vnode() functions take a fs_volume*
instead of the volume ID. So does vfs_get_fs_node_from_path().
- Added type and flags arguments to publish_vnode() and the
get_vnode() hook and removed the type argument from lookup() hook.
Added vnode::type using formerly unused bits to store the node type.
Simplified a few things in the VFS due to the now always available
node type.
- Added fs_volume_ops::{create,delete}_sub_vnode() and
fs_vnode_ops::get_super_vnode() hooks. They are used to support file
system layers, e.g. allowing to extend an FS not supporting BeOS
attribute with attribute support. Needs some more work in the VFS.
- Added fs_vnode_ops::create_special_node() hook for creating special
nodes (e.g. FIFOs).
* Adjusted the built-in file systems and BFS according to the interface
changes. Removed all other FSs from the image for the time being.
We'll see whether further API changes are necessary before porting
them.
* Adjusted the bfs_shell accordingly.
* Implemented create_special_node() in rootfs to support special nodes.
* Added support for FIFOs:
- Added syscall _kern_create_fifo() (used by mkfifo()), which creates
a special node (type S_IFIFO) in the respective file system.
- When a special node is published the VFS creates a respective sub
node. Currently only FIFOs are supported.
- Added a little support for FIFO subnodes by using functionality from
the pipefs.
- Added mkfifo to the image. It can create FIFOs in the rootfs, but
the FIFOs aren't really usable ATM, since they still work like
pipes, i.e. readers and writers need to have them open at the same
time.
* Some smaller changes in the VFS:
- Made the *_CALL macros nicer to use (vargs).
- Refactored FS entry lookup into new function lookup_dir_entry().
- create_vnode() no longer just calls the FS create() hook. First it
looks up the entry and uses open_vnode(), if it already exists. This
is necessary for two reasons: 1) The FS might not support create()
while still allowing to open() entries. 2) When the FS has other
layers on to of it (or the respective node) it might not be
responsible for opening the node.

functions by ones reading /etc/{group,passwd}.
* Added quasi-standard getpwent_r() and getgrent_r().
* Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf()
constants.
* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
should be on the image (executables: 755, others: 644). Otherwise only
root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
for adding additional users and groups (by default only root user and
group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
features have become available.
* Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used
a wrong variable name before.

* Implemented support for pthread_cleanup_{push|pop}().

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24704 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Added a "root" vnode to the io_context. It is used for resolving
paths and converting nodes to paths instead of sRoot. Some more
passing around of io_context structures was necessary.
- Introduced a new lock sIOContextRootLock to protect
io_context::root. The current uses of io_context::io_mutex
(put_vnode(), remove_vnode() while holding it) looked too suspicious
to use that mutex in vnode_path_to_vnode().
- Added _kern_change_root() syscall and chroot() libroot function.
- Added chroot coreutils program to the image. Funnily it seems to be
much easier to set up a little jail than under Linux (just copy
bash and libroot.so into respective subdirs; mount another pipefs
if you want pipe support).
With Haiku allowing direct access to directories via inode IDs
jailing is obviously not very secure at the moment.
- Added /var/empty to the image. It will be the chroot target for ssh.
* Changed vfs.cpp:get_cwd() so that the io_context::io_mutex is no
longer held when calling dir_vnode_to_path().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24673 a95241bf-73f2-0310-859d-f6bbb57e9c96
- The kernel stores the group IDs in the team structure. They are
correctly inherited on fork() and load_image_etc().
- Implemented getgroups() for real, i.e. it retrieves the groups
associated with the process.
- Implemented setgroups(), initgroups() and (the BSDish)
getgrouplist(). The latter two read the group information from the
"group database" /etc/group (if existing).
- Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
relative, since we used stat(), which, in the kernel, uses the kernel
IO context.

finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.

readlink() function. It is no longer required to null-terminate the
string, shall not fail, if the buffer is too small, and shall return
the length of the string actually written into the buffer.
* Adjusted rootfs, devfs, and bfs accordingly. Also adjusted their
read_stat() hooks to return the correct symlink length in st_size.
* Our readlink() does now comply to the standard (and BeOS).
Additionally if the buffer is big enough it is nice to non-conforming
apps and null-terminates it.

BeOS R5's glue code incorrectly calls _thread_do_exit_notification()
when main() returns, while Haiku does that in exit(). Therefore when
terminating this way the exit hooks were called twice for executables
built under BeOS R5. This caused e.g. NetPositive or the R5 svn to
crash on exit (our network code actually uses those hooks).
Fixes bug #1742.

As (our) gcc unfortunately uses atexit() to clean up lazily initialized static
variables inside functions we have to ensure that we do the right thing with
unloadable shared objects. In case a shared object was unloaded that installed
an atexit() hook the application would crash on exit. We now implement a
callback into libroot that is used to call all the atexit() hooks of a
component that is to be unloaded. Most prominently this fixes the media_server
crash at shutdown.

23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.
Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.

from the internet. We get the same result as on Linux, so I think
this is good. I will test it more with WebKit later.

* get_signal_stack() checked the wrong sig_action field (index is signal-1), also,
it had an off-by-one error in the stack range check.
* factored out a restart_syscall() function to avoid code duplication
* arch_setup_signal_frame() relied on the fact that vregs and the signal stack code
is a multiple of 4 bytes in size.
* Fixed sigaction(): it did return the error code directly instead of setting errno.
* signal() actually had a work-around for the broken sigaction()...
* Replaced the sig_func_t typedef with a sighandler_t typedef - this is non-standard
anyway, but now we're at least compatible with the GNU world instead of introducing
our own solution (BSD seems to use sig_t here, BTW).
* Removed now unused sigval structure from the header; it should be added again as
soon as we start supporting it.
* SA_RESETHAND and SA_ONESHOT are the same thing; the former did not work before.
* Made the non-standard SA_* flags refer to the standard ones instead of the other
way around.
* Added a test application for various signal features - works fine under Haiku,
tested also under Linux and BeOS (the latter fails as it does not support SA_RESTART).
More tests should be added, though.
* Cleanup.

for _kern_load_image().
* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
and report all missing libraries. This fixes bug #1324.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
compile with _LOADER_MODE defined.

This does prevent the unwanted side effect of reading or writing at the current
file pointer position when the functions are called with a -1 position.
It's save to do this check in user space, because calling the _kern_* function
with -1 pos has the same effect as calling the normal read/write posix functions.

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break

the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.
We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.
